Background: Oropharyngeal mucositis (OM) is one of the primary complications arising during oncological treatment, which significantly reduces the patient's quality of life (QoL). The aim of this study was to translate, culturally adapt, and validate the use of a new Spanish version of the Oropharyngeal Mucositis-Specific Quality-of-Life instrument (OMQoL) for pediatric patients.
Methods: A multicentric, cross-sectional validation study was conducted to translate and adapt OMQoL from English to Spanish for its use by children with OM aged 8-16 years.
